Exploration of (N3N)ZrNMe2 (1, N3N = N(CH2CH2NSiMe3)33-) as a catalyst for the cross-dehydrocoupling or heterodehydrocoupling of silanes and amines suggested silylene reactivity. Further studies of the catalysis and stoichiometric modeling reactions hint at α-silylene elimination as the pivotal mechanistic step, which expands the 3p elements known to engage in this catalysis and provides a new strategy for the catalytic generation of low-valent fragments.

Coutant, Beatrice,Quignard, Francoise,Choplin, Agnes
, p. 137 - 138 (1995)
Silica supported zirconium hydride complexes activate stoichiometrically and catalytically the Si-H bond of primary, secondary and tertiary organosilanes, R4-xSiHx, R = alkyl, aryl.

, p. 2125 - 2129 (2014)
A strategy for synthesis of the 2-phenyl-2-hydro-1,3-oxa-6-aza-2-silacyclooctane doubly tritium-labeled (2,4- or 2,6-) at the benzene ring has been elaborated. The products are sources of the silyl cations having the atrane structure.

We report a simple and effective nickel-based catalytic system, NiCl2·6H2O/tBuOK, for the electrophilically activated hydrosilylation of terminal alkenes with primary silanes. This protocol provides excellent performance under mild reaction conditions: ex
Specific Z-Selectivity in the Oxidative Isomerization of Allyl Ethers to Generate Geometrically Defined Z-Enol Ethers Using a Cobalt(II)(salen) Complex Catalyst

Enol ether structural motifs exist in many highly oxygenated biologically active natural products and pharmaceuticals. The synthesis of the geometrically less stable Z-enol ethers is challenging. An efficient Z-selective oxidative isomerization process of allyl ethers catalyzed by a cobalt(II) (salen) complex using N-fluoro-2,4,6-trimethylpyridinium trifluoromethanesulfonate (Me3NFPY?OTf) as an oxidant has been developed. Thermodynamically less stable Z-enol ethers were prepared in excellent yields with high geometric control. This methodology also demonstrates the effectiveness in controlling the Z-selective isomerization reaction of diallyl ethers at room temperature. This catalytic system provides an alternative pathway to extend the traditional reductive isomerization of allyl ethers.
